Shaft Clamping Block CNC Machining

Designed for positioning and locking rotating shaft systems, this rectangular block features a large central bore and side slits to securely clamp external tubular or shaft components. Threaded holes on the side walls accommodate fastening bolts, generating radial clamping force through material elastic deformation. It is commonly used in automation transmission modules, fluid pipeline supports, or robotic arm joint connections.

The part surface retains clear machining marks, characteristic of CNC milling, with rounded corner chamfers to optimize stress distribution and prevent assembly interference. Precise control of the positional tolerance between the central through-hole and side threaded holes is critical to ensure concentricity during clamping. Strict control of slit width tolerance and parallelism of the clamping surfaces is also required to prevent shaft misalignment or slippage due to uneven force distribution.

Leveraging our high-precision machining centers and CNC milling production lines, we enable efficient mass production of such multi-hole, complex-profile components, supporting full dimensional inspection from raw material to finished product. Adhering to the IATF16949 quality management system, we strictly control threaded hole depth, perpendicularity, and appearance consistency, meeting the stringent stability and reliability requirements of the automotive, hydraulic, and industrial automation sectors.
